The ROBOfiber HGW-402LM is a hardened, 6-port Layer 2 managed Industrial Gigabit Ethernet switch engineered for extreme-environment deployments. Housed in a rugged IP40 metal enclosure, it features four 10/100/1000Base-T(X) RJ45 copper ports and two 100/1000Base-X SFP slots for flexible optical connectivity. Built to operate reliably in harsh temperatures ranging from -40°C to +75°C, this managed switch supports a variety of crucial Layer 2 capabilities, including STP/RSTP, IEEE 802.1Q VLAN, QoS, port mirroring, and IGMP snooping. It features robust 8kV surge protection on all twisted-pair ports and accepts redundant dual DC power inputs to ensure uninterrupted network uptime in industrial settings.

Key Features & Specifications

  • Copper Interfaces: 4x 10/100/1000Base-T(X) RJ45 ports with 8kV surge protection.
  • Optical Interfaces: 2x 100/1000Base-X SFP slots (transceivers sold separately).
  • Management & Protocols: Web-based and SNMP v1 management; supports STP/RSTP, IGMP snooping v1, IEEE 802.1Q Tag VLAN, port VLAN, QoS, CoS, bandwidth control, and cable diagnostics.
  • Power Input: Redundant dual DC inputs (10-56V DC) with reverse power polarity protection.
  • Environmental Ratings: Hardened for extended operating temperatures from -40°C to +75°C.
  • Enclosure & Mounting: IP40 rated rugged metal housing; includes DIN-rail mounting kit.
  • Compliance: Industrial Grade EMS, EMI, EN61000-6-2, EN61000-6-4 certified.

Frequently Asked Questions

Does the HGW-402LM switch come with a power supply?
No, this industrial switch requires an external DC power source (10-56V DC). It features redundant dual DC inputs typically powered by standard industrial DIN-rail power supplies.
Are SFP transceivers included with the switch?
No, the two 100/1000Base-X SFP slots are unpopulated. Standard MSA-compliant Gigabit or Fast Ethernet SFP transceivers must be sourced separately depending on the required fiber type and transmission distance.
What network management interfaces are supported?
The HGW-402LM provides management via a web browser interface and SNMP v1, allowing engineers to configure features like VLANs, STP/RSTP, bandwidth control, and port mirroring.
